Default Capacitors can you hear the difference

Hi folks , has anyone replaced an inexpensive capacitor with an expensive one in a speaker crossover, I have built a troels gravessen design 3 way speaker and the capacitors that I am thinking about replacing are for the midrange speaker a SEAS ER18RNX, they require between 80 and 100 uf
I have fitted 4 clarity cap esa 22uf, im thinking about replacing these with

1. mundorf supreme
2. jantsen superior z cap
3. audyn cap plus

Would I see an improvement in sound quality or should I save my money.

Certainly you will never see any improvement as long as the crossover is hidden inside the cab.

He was implying that the capacitors won't sound different, just look different.

Guess the general feeling is capacitors don't make a difference.

And, almost without fail, the more expensive the capacitors are the better they'll sound according to the "golden ears".

I wouldn't say that. The correlation between "better" and "more expensive" is pretty weak, though. And "better" is very dependent on exactly how the cap works in a given crossover.

ESR, ESL, and microphonics are the most important parameters to consider, and again, depending on the filter design, "lower" may not necessarily be "better" for the first two.

Be highly skeptical of marketing claims for expensive caps!

I've heard a difference between caps. I replaced some Solens with Auricaps and could definitely hear a difference. I also replaced the orange drops with Russian PIO caps and could also hear the difference, this in a pre-amp and amp respectively. Neither set of replacement caps cost much so it wasn't the money that made them sound better. I've heard that wound up Franklins in oil sound really good though .
